This pilot study found that delta binaural beats improved sleep quality and mood in participants, especially by reducing anxiety and anger. The study showed that listening to binaural beats for 90 minutes led to better sleep metrics, including fewer awakenings and improved sleep duration, and positively impacted mood upon waking. The results support the potential use of sound therapy, particularly binaural beats, as a low-cost alternative to traditional treatments for sleep and mood disorders. 

This study explores the effects of a 3-Hz binaural beat on sleep stages, particularly slow-wave sleep (N3), and found significant positive results. Participants exposed to the binaural beat experienced longer N3 sleep duration, shorter N2 sleep duration, and shorter latency to N3 sleep compared to the control group. This suggests that binaural beats can positively influence deep sleep, which is crucial for physical and mental restoration, supporting their potential use in sound healing for improving sleep quality.
